[Solved] Why the “break” in the loop doesn’t fuction [closed]


You are initialising your birthdaypeople array everytime in each iteration which is why the else block is never executed because for every j the birthdaypeople array is new and have false value. Take out the array declaration out of the for loop.

 boolean[] birthdaypeople = new boolean[n];
  
 for (int j = 0; j < n; j++) {
     int birthday = (int) (Math.random() % n);
     if (!birthdaypeople[birthday]) {
         birthdaypeople[birthday] = true;
     } else {
         peopleindex[j + 1]++;
         break;
     }
 }
